N2 - A new TSV formation methodology based on advanced Directed Self-Assembly (DSA) with nanocomposites consisting of nano metal particles and block-co-polymers is proposed in this paper. Cylindrical nano-ordered structures are formed in Si deep holes through phase separation of polystyrene-block-poly methyl methacrylate polymers (PS-b-PMMA). The impact of molecular weight of the polymers, composition (PS/PMMA ratio), and phase separation temperature on the morphologies is discussed. In addition, simulation results using Self-Consistent Field (SCF) theory are introduced to make fine-pitch TSV.
